The combination of progressive cerebellar degeneration, hypogonadotropic hypogonadism and chorioretinal dystrophy defines the rare Boucher–Neuhäuser syndrome (BNS), which has recently been linked to autosomal-recessive mutations in the PNPLA6 gene in four index patients. Here we present two novel unrelated patients with BNS, where we identified four(More)
Clinical evaluation and mutation analysis was performed in 51 consecutive probands with severe eye malformations - anophthalmia and/or severe microphthalmia - seen in a single specialist ophthalmology center. The mutation analysis consisted of bidirectional sequencing of the coding regions of SOX2, OTX2, PAX6 (paired domain), STRA6, BMP4, SMOC1, FOXE3, and(More)
Jalili syndrome denotes a recessively inherited combination of an eye disease (cone-rod dystrophy) and a dental disorder (amelogenesis imperfecta), which is caused by mutations in the CNNM4 gene. Whereas the ophthalmic consequences of these mutations have been studied comprehensively, the dental phenotype has obtained less attention. A defective transport(More)
Ocular coloboma is a common eye malformation resulting from incomplete fusion of the optic fissure during development. Coloboma is often associated with microphthalmia and/or contralateral anophthalmia. Coloboma shows extensive locus heterogeneity associated with causative mutations identified in genes encoding developmental transcription factors or(More)
Jalili syndrome1 is a rare autosomal-recessive disorder, which is caused by mutations in the CNNM4 gene.2,3 Two phenotypes are proposed: associated with bull’s eye maculopathy and peripheral retinal degeneration (type A), or with minor retinal dystrophy (type B).4 We report two new cases (siblings of 15 and 16 years of age) with different retinal findings,(More)
Bilateral preretinal and vitreous hemorrhages in infants are rare and can present a diagnostic challenge, with nonaccidental trauma included in the differential diagnosis. We present the case of a 4-week-old boy in which a Pierre Robin sequence and a positive family history led to the clinical diagnosis of Stickler syndrome, which was confirmed by the(More)
Inherited monogenic diseases of the retina and vitreous affect approximately 1 in 2000 individuals. They are characterized by tremendous genetic heterogeneity and clinical variability involving mutations in approximately 250 genes and more than 20 different clinical phenotypes. Clinical manifestations of retinal dystrophies (RDs) range from mild retinal(More)
PURPOSE To identify the genetic cause of autosomal recessive familial foveal retinoschisis (FFR). METHODS A female sibship with FFR was identified (Family-A; 17 and 16 years, respectively); panel based genetic sequencing (132 genes) and comparative genome hybridization (142 genes) were performed. Whole-exome sequencing (WES) was performed on both siblings(More)
Irreversible disability in multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) is largely attributed to neuronal and axonal degeneration, which, along with inflammation, is one of the major pathological hallmarks of these diseases. Optical coherence tomography (OCT) is a non-invasive imaging tool that has been used in MS, NMOSD, and(More)
Color anterior segment imaging showing a bilateral congenital lamellar cataract in a 6.5-year-old girl (visual acuity, 20/70). Small central opacification and peculiar posterior disruption of the cortical alignment are visible in both the right eye (A) and the left eye (B). Visual acuity improved to 20/25 in both eyes after cataract surgery with intraocular(More)
